There is a learning curveBy SCUBAFreakyon 1/30/2013

SCUBAFreaky would recommend this product to a friend

This is by far the best test kit for measuring Phosphate, but there is a learning curve. As other posters have said there is an art to getting all of the powder in the curvette, but once you get the hang of it, it's no longer an issue. Also this thing will time out after 2 minutes during the phase when you are dissolving the powder. Once it times out, you pretty much have to start over due to the baseline scan. Also be aware that it only comes with 6 reagent packets...and you'll blow through those very quickly due to the learning curve. Unlike other posters, I'm having trouble getting consistent measurements, but all that said, the Hanna Checker is best phosphate checker I've used so far.

Works Great and Easy to use if you open the package on two sidesBy Charles on 1/24/2013

Charles would recommend this product to a friend

Just cut two sides off of the regents package and them trim the corner off at the tip, open and pours in with ease.
Do this before you put the water in the machine andit won't time out.

I was using Salifert test kit and I could never get a accurate reading. Now with this Checker I have a way better idea as to what my phosphate levels are.

I gave it 4 stars because it is a little hard to get the powder in the vial the first time but after some practice its no biggie.

Picked this up on a black Friday doorbuster deal, and couldn't be happier. There was a little learning to be done on how to use the device, but once that was done, I can quickly and confidently test my levels in my tank and make necessary adjustment. Also BRS came through on shipping with a 2 day turnaround, Amazing!

Consistent and accurate!! By Ryanon 12/22/2012

Ryan would recommend this product to a friend

Consistent and accurate!! If you are keeping corals you should get this. The test kit that I have been using always tests way lower than the hanna checker so I've always thought my phosphates were more in check than they were. Now that I know where my phosphates actually are. I have been able to get them more under control and have noticed an increase in coral growth already.

Hanna Checkers are downright awesome. Accurate, digital, takes less than five minutes. They are the best meters I have every used.

Ok but be carefulBy Granton 12/5/2012

Grant would recommend this product to a friend

In the instructions it says after adding the reagent to shake for 2 minutes. But the colorimeter turns off after 2 minutes. So I have wasted 2 of the reagent packets out of the few that come with it and have yet to accurately test my water.

Obviously a user error but just a tip.

definately worth the purchaseBy DANIELon 12/1/2012

Love the precision of the digital readout. No more guessing color shades. 5 stars. Minor item(s) - only 6 tests provided with kit. Also, small amount of effort to learn how to pop off plastic lid cleanly.

Check it, mateBy Old Salton 11/30/2012

Old Salt would recommend this product to a friend

Well worth the investment and once you get the hang of dumping in the powder--can be dicey at first--it's very easy to use. You do have to keep buying the reagent, but I use my checker sparingly, mainly to check up on an API kit that I use 2-3 times a week. The combination allows me to keep a close eye on phosphates.

Great ProductBy williamon 11/28/2012

I currently have the Calcium, ALK, and Phosphate checkers, and they make testing the water amazingly easy. I was using ELOS kits before hand and these take 1/2 the time the others do. I still test with elos bi-monthly to ensure the Hanna's are still reading correctly. Wish they had more regents with the initial purchase.

OK but hard to use properlyBy Andyon 11/28/2012

Andy would recommend this product to a friend

I only recommend this because the alternatives are horrible or a lot more money. It is very hard to get all of the powder reagent out of the package, and opening the package properly and actually getting the powder in the vial is an art unto itself. This part will take you a few minutes alone. Then the joy begins when you try to get the powder to actually dissolve, and then stop bubbles on the cuvette. If you don't get it dissolved or free from bubbles, the results will be wildly off. I tested the same water with bubbles on the glass and without. With bubbles it was saying the phosphate was 5ppm! Without bubbles, 0.01ppm.

Subodh would recommend this product to a friend

ok, I'm assuming everyone did their homework and the numbers shown by this thing are perfect and tested.
Just kidding, I cross-checked with the Red Sea kit. Hanna showed me 0.13 and red Sea Phosphate check came up between 0 and .25 Close enough for me.

I did take the one star off because - how the heck is one supposed to get all the darn powder from that pouch into the vial with that tiny a hole? I'll tell you how but not before I had to rack my brains. Get a clean sheet of A4 size paper, tear open the sachet, drop everything onto the paper, now lift it up and make a cone shape, drop the powder into the vial.

I almost took off another point for packing just 6 sachets. But well, it works well, instructions are clear and concise and no more asking the wife to read the damn colors. I guess I'll try the other Hannah checkers as well.

hell i just got my hanna hi 713 today all excited to test phosphate.
so i open it and go step by step testing my water waiting on this high reading to show up because i have algae growing every where. well is shows 0.00 on test one I think well that cant be right so i test it again same deal 0.00 ok so i text my tap water 0.03
so there is 3 of my 6 test wasted imo, I know the tank has po4 i got this with a gof reactor to test weekly to me it dont seem to work

Easy enoughBy Edwardon 9/28/2012

Edward would recommend this product to a friend

There are two reasons I gave 4 stars instead of 5. First is that the syringe that is used to get the reagent does not always attach firmly to the tip supplied. As such, it can drip out and you have to push the tip on again. The second reason is that at the levels of phosphate I run (reef), I wish BFS carried the ULR phosphorous Hanna Checker. Even though it is not phosphate, you can calculate that by multiplying by about 3. That unit has more accuracy and can read a little lower. But I suppose the phosphate one cannot be faulted as it does what it is supposed to and is easy to use other than the tip on the syringe.

it is nice to be able to know for sure what your tanks levels are. for me there was a little bit of a learning curve and i used a lot of the reagent. you should buy extra reagent when you make your purchase. you do need to use caution opening the cap or you could break it.over all i am very pleased and glad i bought it.

Accurate, but...By jameson 9/22/2012

james wouldn't recommend this product to a friend

I absolutely loathe the reagent packets.

I wish it was a liquid reagent like the Hanna Alk, but unfortunately it is not. Instead (as another poster mentioned) you have to dump the contents of a small packet of powder into the hole of one of the test vials. It makes it a bit of a pain to work with.

Join the Revolution wouldn't recommend this product to a friend

Do not buy it. Go Salifert, or other means. This test would be a great if it was designed to work with ease. This test tries to be innovative ,but titration is much easier and guessing is eliminated. Who wants to pour a small pack of powder into a small hole the diameter of a dime???! The lid is difficult to open and the instructions are so 3rd world. Next..

The meter seems to work fine, but be made of cheap plastic. The second or third time I snapped the lid open, it came off. It looks like there are only two small ultrasonic welds that hold the top part on. The meter still seems to work fine, but I have to keep pushing it back together every time I open the lid.

EssentialBy Robert on 8/23/2012

Robert would recommend this product to a friend

I have the low-range phosphate colorimeter.

Upon receiving, I opened the top of the unit and the entire top white part separated from rest of the body (the small plastic pins holding it sheared away)--a rather inauspicious start. It is still usable and I don't want to screw around with returning it--despite BRS and their excellent return policies.

I just have to hold the white part against the rest of the body and it works OK.

WATCH OUT for the regent. Use a scissors and OPEN CAREFULLY! This stuff has a very low PH and will irritate skin noticeably. In addition, the reagent is a little tricky to pour out of the envelope which can increase risk for accidental spillage. Again, use care with this reagent.

Other than questionable quality or quality control of the physical unit and the nasty reagent, I cannot possibly imagine living without this essential instrument.

What an awesome product! LOVE this tester.By Chuckon 8/13/2012

Chuck would recommend this product to a friend

For anyone's who's used the 'other' phosphate testing kits, we all know how crazy-difficult it is to read which super-duper light shade of blue the result is to get a phosphate reading -- basically inaccurate/impossible and something I stopped doing often because it was a waste of time. NO MORE! After getting the Hanna phosphate checker, it completely takes the guess work (and eye-straining) out of phosphate testing. I almost feel spoiled having the digital read-out of the phos level after struggling with other test kits for years. This is one of the best and easiest tools, along with a nice refractometer, that I have for my 240g mixed reef. And with this low of a price tag, it's a no-brainer that every aquarium owner should have one.

Fell apart after 3 usesBy Nathanon 8/3/2012

Nathan wouldn't recommend this product to a friend

Don't get me wrong, this thing is easy to use and works great, but it fell apart after the 3rd use. The top detached from the base so now when I use it I have to try and hold the top on so it doesn't fall off. I have tried to contact Hanna about this issue two separate times and have received no response.

It works great and I understand you run into issues with products from time to time, but receiving no response from a manufacturer is unacceptable.

The best consumer phosphate tester by far.By NanoCabanaon 6/17/2012

NanoCabana would recommend this product to a friend

This is an affordable and accurate tester for phosphates. Like many, I was tired of trying to match color shades on a card. With Hanna's digital readout, I have confidence that my weekly test can be compared for trends. I also use this for my planted freshwater tanks and will buy Hanna's iron checker in the near future. Good job Hanna!

This Test kit is very nice because you get an accurate digital reading. If you are worried about your phosphate levels and want to make sure you have them under control you need this product. For the price of the test kit I feel like it should of came with more reagents to perfom test. As of now it only comes with 5 so you better buy extra refills. Only other complaint I have it the powder reagents is hard to get into the small vile. I would recomend getting this product with your GFO reactor.

If you are considering running GFO in your tank this is the way to go, This instrument is very precise and accurate. It is much nicer knowing exactly what your PO4 is rather than guessing it is somewhere under .25.

A cheap, flimsy, warped and very difficult to open case greets you when you first try to access this kit! Kind of like having a cheap and dysfunctional door handle on a fancy new car....

Other than the above, seems to work great and consistent and is easy to use once you free it from the cheapy case...
